Lawyers representing the three detectives charged in the 50-shot barrage of bullets that killed Sean Bell on his wedding day confirmed yesterday they will seek a change of venue.

Detectives Michael Oliver, Gescard Isnora and Marc Cooper – who are all due back in court tomorrow – are set to go on trial in Queens in January.

But Isnora’s lawyer, Philip Karasyk, said the defense will ask the Appellate Court to move the case.

In court papers, Isnora says he saw Bell and his two pals argue with a man outside a Jamaica strip joint Nov. 25, 2006, and heard one of Bell’s friends yell he was going to get a gun. Cops soon unleashed a barrage of bullets, killing Bell. Neither he nor his pals were armed.
